JEAN LOUIS JOIRIS, OF WANDRE, BELGIUM.

SHOTGUN AND THE LIKE GUN.

To all fio/.0171 t may concern.

Be it known that l, lean Louis Jonas: manuitcturer, a subject oi the King` of Belgium, and resident of lVandre, in the King'- dom of Belgium, have invented certain new and useful vmprovements in Shotguns and the like Gunsgiand l do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reterence being had to the accompanying drawings, and to letters or figures ol reference marke-d therein7 which 'term a part oii this specification.

This invention relates to a double bar rcled shot gun having a single trigger.

rFhis gun has two hammers each resting in the cocked position on` a scar7 each of these two hammers being adapted to be cocked and released separately.

Vilhen these two hammers are cocked simultaneously@ the first action on the trigger releases one of the hammers and the second operation 'of the trigger releases the other.

One of' the sears is lirmly attached to the trigger and has a movable abutment adapted V*to bear against a catch carried by the scar and adapted according to its position to farry with it or release the second scar.

This movable abutment may be under the action ot a spring tending to bring it into the position where it controls the displacew ment of the second scar, the action ol this spring being overcome when the hammer bearing against the tirsJ sear is cocked by a nose carried by this hammer so that this abutment is in the position in which it does not involve the displacement ol" the second scar.

This mechanism may beV completed by a safety piece locking the said second scar as soon as the iirst scar has commenced its dis` placement and liberating it as soon as the trigger has resumed its position of repose.

rlhe invention will be more particularly described with reference to the accompanying ('lrawings yin which Vliigure l is a perspective view ot the (ire-- arm with a part broken away showing the trigger, the sear which is connected with it and the rst hammer bearing upon this sear.

Fig. 2 is a view in perspective of the gun with a part broken away showing the second scar and the second hammer.,

Fig. G the same safety piece in its position relative to the barrels and the scars.

l`ig. 7 shows the second scar illustrated in Fig. 4l; on another iace.

ln Figs. l and 2 the. hammers l and 2 are in the uncooked position, they are pivoted on the pin il and are cach provided with two stop notches LL and 5, those ot thc hammcil l being :ulapted to hear against the scar (i and those oi the hammer 2 ou the scar 7. These sears which are specially shown in liigs. 3 and 4I: are pivoted on the pin lll. The Ahanuner lV has lurthe' a nose 9 which acts when the hammer is cocked, on the movable abutment f) carried by the scar 6 in such a way as to disi'ilace it, as shown by tl arrow X', against the action ot a. spring ll), and to bring it into such a position that it does not carry with it the abutment 12 attached to the scar 7. This abutment .i2 has an cseapement piece i3 pivotcd at lei: upon it intended to give passage, to the 1novable abutment 9 when this abutment is displaced as shown by the arrow X. The capcment piece lf3 bears against the sear 7 by spring pressure.

rll'he sear 7 has at its lower face a spring 25 acting constantly on the plate 2G ot the trigger 27 and allowing this scar 7 a, displacement relatively to the said plate 2G when during the cooking ol the hammer 2 the catch notch 5 pushes it be'liore taking sumiorton it.

The working of the weapon is as follows lhen the hammer 2 is cocked its stop notch 5 bears on the projectionv 2? oi the scar 7. During the cocking oi the hammer l the nose S causes a displacement in the direction indicated by the arrow X, of the movable abutment 9.

The stop notch 5 ot this hammer l before resting on the projection 21 of' the scar G causes a slight displacement ot this scar against the action ot the spring 2S ol the trigger 27, and during this displacementthe escapement piece 13 allows oli the passage of the movable abutment 9 without ncces sitating'a displacement olf the scar 7.

When the hammer l is cocked its stop notch 5 bears on the projection 2l of the scar 6 and the movable abutment 9 is rektained by the nose 8 of the hammer 1 in firing of the hammer l the nose'S has abandoned it.

When the trigger 27 is allowed to return to its position of repose, the removable abutment 9 is brought back in rear of the escapement piece 13 on which it takes support and obeying the action of its spring 10 assumes such a position that when the trigger 27 is afresh acted on, it will abut against the catch 1:2 and by this fact draw the tumbler 7, which will cause the firing of the hammer 2. This mechanism is completed by a safety I piece 15 provided with a prolongation 16 entering the l groove 17 of the action body (Figs. 1 and 2) and through which a pivot 18 passes. This piece 15 comprises a rib 19 adapted to engage 'between the projections 2() andV 21 of the sear 6 and a linger 22 adapted Yto abut against the projection Q3 of the sear 7 so as to cause the locking of this latter. This safety piece is constantly induced to cause this locking owing to a spring 24 acting on it.

As soon as, in consequence of the action on the trigger 27, the sear 6 commences to turn about its axis 11, the rib 19 of the part 15 penetrates between the projections 201 and 21 of the sear 6, and consequently the finger '22 abuts-against the projectionQB of the Sear l one or other of the two hammers is cocked separately its firing is caused by the first action on the trigger."

Tt is evident that the principle of the trigger `mechanism forming the object of the present invention may be applied to any kind of firearms such for example as pistols or revolvers.

AVhat I claim is: v

l. A double-barreled gun comprising two hammers, a single trigger pivotally mounted on a pin, a sear for one of the hammers attached firmly'to the trigger, a second sear for the other hammer pivotally mounted on the aforesaid pin, and a movable abutment on the first sear adapted according to its position to operate and to release the seeond sear.

2. A double-barreled gun comprising two hammers, a single trigger pivotally mounted on a pin, a sear -for one of the hammers attached firmly to the trigger, a second sear for the second hammer pivotally mounted on the aforesaid pin,.a movable abutment on the first sear adapted according to its position to operate and to release the second sear, a spring pressing vsaid'movable abutment toward the position 1n which it causes the displacement of the second sear, a nose on the first hammer acting on the movable abutment against the spring pressure when the hammer is cocked, for bringing said abutment into the position in which it does not operate the second sear.

3. A double-barreled gun comprising two hammers, a'single trigger pivotally mountedon a pin, a sear for one of the hammers attached firmly to said trigger, a second sear for the second hammer pivotally mounted on the aforesaid pin, a movable abutment on the first scar adapted according to its position to operate and to release the second sear, a safety piece pivotally mounted in the action body, a rib on said safety piece adapted to penetrate between two projections of the first sear, in consequence of the displacement of the first sear, a slope on one ofsaid projections acting'on a slope of the aforesaid ribv for moving the safety piece when the trigger has returned to its position of repose, and. a finger on said safety piece,

adapted to abut against a projection of the second sear when the rib ,of said piece is in engagement with the two projections of the first sear. Y

4. A double barreled gun comprising two hammers, a single trigger pivotally mounted on a pin, a sear for one of the hammers attached firmly to the trigger, a second sear for the second hammer pivotally mounted on the aforesaid pin,l a movable abutment on the first sear adapted according to its position to operate and to release the second sear,

a spring` pressingsaid movable abutment toward the position in which it causes the displacement of the second sear, a nose on the first hammer acting on the movable abutment against the spring pressure when the hammer is cocked, for bringing said abutment into the position in which it does not l operate the second sear, and an escapement `piece arranged on the second sear for allowing of the displacement of the movable abutment.

In testimony whereof I affix my signature in presence of two witnesses.

JEAN LOUIS J OIRIS.
